Subsoiling and fertilizing machine for tea gardens

Abstract

The invention discloses a subsoiling and fertilizing machine for tea gardens. The machine comprises a rack; a fertilizer box is arranged above the rack; a depth wheel and a subsoiler are arranged under the rack; a gearbox is also installed above the rack; one output end of the gearbox is connected to a tractor; other output ends of the gearbox are connected to a fertilizer stirring device inside adischarge port of the fertilizer box; one end of a fertilizer delivery pipe is connected to the discharge port and the other end extends to a side, back to the soil, of the subsoiler. The subsoilingand fertilizing machine for tea gardens of the invention has the structure matched with the size of the tea tree rows, and is suitable for working across the tea tree. The structure of the whole machine is compact, and the distance between the subsoiling and fertilizing ditch and the root of the tea tree is appropriate, which is not easy to damage the root, but also has a strong improvement on thesoil structure and fertility of the root. The whole machine and the tea garden tractor are connected by hooking, which is convenient for assembly and disassembly. The structure of the whole machine is firm, the strength and rigidity are very high, and four grooves can be operated at one time, and the work efficiency is high.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a subsoiler fertilizer applicator. Background technique [0002] Tea trees are mainly planted in areas with poor soil such as hills and slopes. Deep loosening and fertilization of tea gardens can improve the yield and quality of tea. Subsoiling can improve soil water permeability and air permeability, and the application of organic fertilizer can improve the fertility of tea garden soil. Combining subsoiling and fertilization can accelerate the decomposition and utilization of fertilizers, reduce the number of times that machines enter the ground, reduce energy consumption, and save costs. But at present, the subsoiling fertilizer applicator that uses for tea garden is also very lacking, and existing subsoiling fertilization machine is mainly used for orchard, or is used for the subsoiling fertilization of crops such as wheat and corn.

AI Technical Summary

Problems solved by technology

[0004] The matching degree of the subsoiling fertilizer applicator to the agronomic requirements is very important. Most of the tea gardens carry out subsoiling and fertilizing from between rows when there are tea trees. Therefore, other subsoiling fertilization machines are not suitable for use in tea gardens.

However, for the only subsoiling and fertilizing machine for tea gardens, a single subsoiling and fertilizing ditch is opened between the rows, the soil loosening and fertilization are too far away from the tea tree roots, and the operation effect is not good enough; the subsoiling shovel handle is fixed by a four-bar linkage mechanism. Connected to the tea garden management machine, the structural rigidity is not very good; two separate fertilizer boxes are used, and the amount of fertilizer is not large enough; the fertilizer discharge device uses a grooved wheel, which has a good effect on the discharge of inorganic fertilizers, but not good for organic fertilizers; The machine is directly installed on the tea garden management machine, which brings great difficulties to the assembly and disassembly of subsoiling fertilization parts, and it is not convenient to realize one machine with multiple functions by replacing the hanging parts
